If local building codes permit, you may be able to save money by putting a corrugated metal roof for your shed or garage (this type of roof is not recommended for a home). A tin roof / corrugated metal is relatively cheap investment, and is durable. Learn how to install a tin roof with this simple method. The materials are indicated for a shed measuring 10 feet (3,048 meters) by 10 feet (3,048 m). Buy more material and trim if necessary.
- Measure the dimensions of the shed or garage roof and add 4 inches (10 cm) on a slope. Take a picture or two if something unusual on the roof. Take your measurements, photos and list of things to buy/need from your local store for home-conditioning and asks for help to find the materials for your roof.
- Ponte thick goggles and gloves. Use the flat blade to scrape off the old shingles and tar paper. Make your assistant help you remove all the old roofs. Stripped the roof sheathing or plywood. Use pliers to pull all the nails that protrude from the surface. If no plywood on the joists, or is in poor condition, first, install a plywood or make a professional install.
- Line the ceiling, using new asphalt impregnated paper (tar paper). Most professional roofers use a hammer stapler to attach the tar paper, but a staple gun, or “big-headed nails” for ceilings (also called nail to paper) work well. Applies to paper clips or nails every 12 inches (30 cm).
- Install tablets together to place the new tin roof. Fix a board of 1 by 4 inches (2.5 to 10 cm) in length at the bottom edge of the roof. The board must be aligned with the edge and with the side of 4 inches (10 cm) lying against the ceiling surface. Direct wood screws of 3 inches (7.5 cm) through of an inch (2.5 cm) board within the beams. If necessary, cut another board 1 by 4 inches (2.5 to 10 cm) long and attach aligned with the first. Add 2 feet (61 cm) and attach another bar in the same way. Work from the bottom to the top of the roof.
- Nail the metal rim around the edges of the roof, using a hammer and hot dip galvanized nails for waterproofing roof or a cordless drill and screws
- Put foils for the first part of the roof. Those are as long as the distance from the top of the roof going 4 inches (10 cm) to the roof edge. Place one of the sheets that go to the other side of the roof, on top, in order to extend about 6 inches (15 cm) through the top. Fold the bottom of the sheet down over the top. Chalks 4 inches (10 cm) of the outgoing, and remove the piece of roof. Cut all the pieces to the other side of the roof of that length.
- Screw the first sheet metal strips together that are below it. Place the screws in the middle and inner edge of the blade, but not in the right. The panels must be able to expand and contract with temperature changes, so do not put nails or screws in all the way. Direct them until just touches the sheet. Tighten only one in the center of the top of each panel.
- Overlay the first channel V of the second sheet in the last channel V of the first sheet, and screw or nail through the two sheets on tablets continues to the left side of the second sheet, and then the center of the second sheet. Remember to tighten the screw or nail only top center. Repeat the process in the same way until you’re ready for the last sheet on that side of the roof. At the edge of the roof, you have to cut the last sheet to fit.
- Repeat Step 3 of Preparation section: sheets installed on the other side of the roof, working from the bottom up.
- Repeat Steps 1 and 2 of section to install the sheets across the roof. Be sure to leave 6 inches (15 cm) outstanding at the peak of the roof. Fold each sheet and screw into place throughout the upper edge before installing the next panel. Alternatively, you can install a vent and a cap on the ridge, but is not required on the roof of a shed.
Tips & Warnings:
Make sure you place the first sheet on either side of the roof is square, because the panels are attached to the previous panels. Wrong a little at first can mean quite finish off. Have a helper or two makes this work go much faster. For simplicity, you can skip the metal rim and leave an excess of film on both sides of the shed roof, as in the bottom.
